What is Leucine?

Leucine is considered as one of the most important of the three branched-chain amino acids (BCAAs) and plays a vital role in the development of lean muscle mass as well as recovery and repair post-exercise. It is thought by many that it should be a vital addition to any athlete or gym enthusiast who is serious about the training and their supplement programme.

Who should take Leucine?

Because leucine is such an important amino acid it should be taken by anyone who takes part in intense exercise and is looking to maintain lean muscle mass to improve performance. With Leucine being an essential amino acid, it cannot be synthesised by the body and therefore needs to be supplemented through diet or extra supplementation. Leucine can be found naturally in meat, fish and dairy and is also present in whey and casein protein. leucine is the most thought of out of the 3 branched-chain amino acids and has had the most research taken out supporting its ability to increase protein synthesis. There are also studies that show leucine can prevent muscle breakdown and increase energy and endurance.

The biggest performance benefit of leucine is its ability to increase protein synthesis which helps in the repair and growth of lean muscle. This can increase performance by increasing power and strength and reducing recovery times. Leucine can also promote the uptake of glycogen and increase glycogen replenishment which is ideal for endurance athletes you severely deplete glycogen levels during long periods of training.

Leucine can be taken at any time of day. We recommend one serving in the morning, one pre-workout and one post-workout. As Leucine is not fully soluble some powder will settle on top of the water, this is perfectly normal. To improve mixability we recommend mixing Leucine with your protein shake.
